The liberation of Berlin refers to the period during World War II when the Allied forces, primarily the Soviet Red Army, conquered the German capital, Berlin, from the Nazis. This event primarily occurred in April and May 1945.
The final offensive on Berlin began in April 1945, with the Red Army launching a massive assault against German defenses around the city. Despite fierce resistance from German troops and fanatical SS units, the Soviets steadily advanced through enemy lines.
Street fighting in Berlin was extremely intense, with fierce battles taking place in various neighborhoods of the city. Berlin civilians also suffered greatly during this time, trapped between the front lines and facing massive bombardments.
Ultimately, on May 2, 1945, German forces in Berlin surrendered, marking the end of the battle for the city and essentially the end of World War II in Europe. The official surrender of Nazi Germany followed a few days later, on May 8, 1945. This event was celebrated as the Allies' victory over the Nazi regime and the end of Nazi terror in Europe.
